通过序列化和反序列化实现深拷贝

.NET中使用Object的MemberwiseClone()方法来实现浅拷贝，通过序列化和反序列化实现深拷贝，后者代价比较大

class FootMan : Enemy
    {
        private string model;
 
        public FootMan(int power, int speed, Location location)
            : base(power, speed, location)
        {
            model = "footman";
        }
 
        public override void ShowInfo()
        {
            Console.WriteLine("model:{0} power:{1} speed:{2} location:({3},{4})", model, power, speed, location.x, location.y);
        }
 
        public override Enemy Clone(bool isDeepCopy)
        {
            FootMan footman;
            if (isDeepCopy)
            {
                MemoryStream memoryStream = new MemoryStream();
                BinaryFormatter formatter = new BinaryFormatter();
                formatter.Serialize(memoryStream, this);
                memoryStream.Position = 0;
                footman = (FootMan)formatter.Deserialize(memoryStream);
            }
            else
                footman = (FootMan)this.MemberwiseClone();
            return footman;
        }
 
        public void FootmanAttack()
        {
            Console.WriteLine("FootmanAttack");
        }
    }
